Yoga Danda is an ancient device, designed by yogis centuries ago. It is a tool to be had by a sincere yoga practitioner, who wishes to harness the power of yoga by balancing of energy.
Energy or Life force or Prana running in our bodies is the basis of our existence- our being. We can attain harmony when this energy is in harmony and in peace. The only way we can harmonise this energy is by controlling our breath pattern.
One part of controlling breathing is by watching and correcting the flow of air through our right and left nostrils. The irregular flow in the nostrils can be regulated by the practice of Pranayama. Yoga Danda helps in changing the flow of breath in nostrils. This allows a person to achieve optimum energy flow in the body. The flow of breath can be altered by supporting the Yoga Danda under the armpits (right or left as per need).
Yoga Danda is of great help to practitioners of Japa Meditation as well. Meditation with mala beads (japa) can be tiresome for the hands at times. So the practitioner can use the Yoga Danda to support his arm holding the beads. It enables a longer, unhindered japa without discomfort.
